Torque in F1 engines

[magracer]

I did a quick search on the net to find out the torque figure in current F1 engines, but couldn´t find a thing...

We all know the last evolution of V10s achieved almost 1000hp, but what about torque? My thesis is that torque figures should be relatively low compared to bhp figures (maybe around 650 lb/ft?).

Any one has a clue?

[Matra et Alpine]

much MUCH lower. Down at 300-350 lb/ft IIRC.

It's one of THE most guarded secrets in F1 :D
Even getting specs on older engines gets difficult.

I thought it was in the region of 300 NM or even less. (about the same amount as my humble diesel)

I can guarantee it's a lot less than 650.....I think the formula for bhp @ given rpm is : bhp = Torque x rpm / 5252. Assuming F1 car makes 900bhp @ 19000rpm, the torque value @ 19000 rpm comes up to something like 262 lb-ft. That's @ 19000 rpm, peak torque is likely to occur at lower rpm at a higher value. But I don't think that value will be much higher, if at all, than 300 lb-ft. As torque is quite displacement dependent.

thank you for repeating the famous formula again, it had slipped my mind when made my earlier post.

Well for next year people are quoting figures like 22000rpm and 750bhp. If that's the case then torque will be down at a measly 180lb/ft at peak power.

It'll probably be scraping over the 200-220lb/ft mark at peak torque. :rolleyes:

is this why some buyers complained about the F50's lack of torque - because it was a f1 derived engine?

lmao does the same go for honda owners?. lol. it makes sense. Carrol Shelby did say something like "horsepower sells cars, torque wins races" so true. c'mon we need torque it's more important than horsepower.

[RacingManiac]

F1 car makes up for it by the incredible ability to make power in a hurry, plus the fact that the car weighs only 1320lb with driver.....

Torque is pretty much limited by the displacement of the engine. For road cars it is rare the torque exceeds 100 Nm per litre, and it has been like this for decades. That's why the big V8s are considered torquey and Honda's small fours not.

that is the case for normally aspirated petrol engines only....

The AER I4 Turbo is a good engine even thought it stalls a lot

An engine does not stall, a lousy driver stalls an engine:D

unless the engine is really knackered.

i had a mate at school whose nova would stall itself :D

crappy Nova with K&N and phat exhaust and NO alterations made to make the ENGINE run properly will lead to that :D

NO properly set up engine stalls "itself" !!!!

Firstly what the hell does this have to do with the topic on hand? Secondly the AER engine is not very reliable, but I have never heard anything about stalling.

starternator.....ah yes....

Did some simulations for the BHP curve and max torque figure would depend on the "quality" of the power delivery at lower revs.

Most probably its around 300 lb/ft as most of you pointed out...damn, that´s low!

The tyre grip and acceleration kind makes the point that more isn't needed !

low Weight - always a winner :D

Aerodynamics for handling beats low weight

Kinda off-topic though :o :p

Worthy of a thread of it's own perhaps as aero seldom wins over weight.
eh more aero needed to get grip in corners to stop the mass overcoming the grip on change of direction ? Not as necessary for lighter cars :D

But it's not one or the other !!!!

it had no mods it was just on its last legs :)
